This bugfix release adds a new dev-mode middleware to catch accidentally dispatching an action creator, adds a new listener middleware option around waiting for forks, adds a new option to update provided tags when updateQueryData is used, reworks internal types to better handle uses with TS declaration output, and fixes a variety of small issues.

Changelog

Action Creator Dev Check Middleware

RTK already includes dev-mode middleware that check for the common mistakes of accidentally mutating state and putting non-serializable values into state or actions.

Over the years we've also seen a semi-frequent error where users accidentally pass an action creator reference to dispatch, instead of calling it and dispatching the action it returns.

We've added another dev-mode middleware that specifically catches this error and warns about it.

Additional Options

The listener middleware's listenerApi.fork() method now has an optional autoJoin flag that can be used to keep the effect from finishing until all active forked tasks have completed.

updateQueryData now has an updateProvidedTags option that will force a recalculation of that endpoint's provided tags. It currently defaults to false, and we'll likely turn that to true in the next major.

Other Fixes

The builder.addCase method now throws an error if a type string is empty.

fetchBaseQuery now uses an alternate method to clone the original Request in order to work around an obscure Chrome bug.

The immutability middleware logic was tweaked to avoid a potential stack overflow.

Types Changes

The internal type imports have been reworked to try to fix "type portability" issues when used in combination with TS declaration outputs.

A couple additional types were exported to help with wrapping createAsyncThunk.
